power controlled automatic weighing ma chines, I

In automatic weighing-machines as constructed prior to this invention the rapidity of piperation is controlled by the successive pre etermined amounts of material which are weighed or measured. As in such Inachines the material is delivered to the weighing-receptacles by gravity, the rapidity of operation depends upon the condition of material, which if dry will readily flow by gravity, and thereby increase the rapidity of OPGIELLIOIl of the machine, but which if moist will flow more slowly and decrease the rapidity of action of the machine.

The primary object of my invention is to provide a I weighing-machine in which the speed of operation will be rendered ositive by controlling the su ply of materia to the weighing-receptacles power-driven mechanism, thereby eliminating the uncertainty in operationdue to the supply of the material being controlled by 4 the weighing or measuring of the material itself.

A further object of my invention is to produce a weighing-machine in which the main supply to the weighing-receptacle will be instantly completely opened and cut off by tripping-weights previously lifted into operative position to be tripped by power.

A further object of my invention is to provide a weighing-machine in which the material will be delivered successively toWeighingreceptacles by an intermittently opening primary or main supply and by a constant secondary or completing supply.

Asill further object of my invention-isto provide a weighing-machine in which the material to be Weighed'will be supplied from a weighing-receptacles, each' receptacle comprising two cornpartments, into which the material is alternately delivered.

My invention has for its final object the provision of a power-controlled automatic weighing-machine which will be comparatively simple in construction, rapid and accurate in action, and eflicient in operation.

My invention, generally described, consists in a plurality of weighing-receptacles each having two compartments, a separate scale-beam supporting each receptacle, a main supply leading to each receptacle, a gate controlling each main supply, power actuated means for alternately tripping weights to open said gates, means actuated by the partial lowering of the receptacles to close therespective gates, a constant powerdriven secondaryor completing supply leading to each receptacle, means. actuated by the complete lowering of each receptacle for discharging the weighed material from one compartment thereof and simultaneously guiding the material into the other compartment, and means for varying the proportions of material delivered" by the main and com pleting supplies according to the rapidity of opening the gates controlling the main supply,'so that after closing each gate the necessary quantity of material to complete the predetermined amount may be delivered by the secondary supply before the gate is again opened.

My invention will be more fully described hereinafter with reference to the accompanying drawings, in which the same is illustrated as embodied in a convenient and practical form, and in which Figure 1 is an end elevational view; Fig. 2, a plan view; Fig. 3, a view similar to Fig. 1, showing the parts in an adjusted osition; Fig. 4:, an elevational view of one si e of the machine looking from the right in Fig. 1; Fig. 5, an elevational view of the op osite side of the machine looking frornthe lift in Fig. 1 and upwardly with respect to Fig. 2 Fig. 6, a detail view showing one of the gates held open; Fig. 7, a central vertical sectional view; and Fig. 8 a detail elevational view similar to Fig. 4, showing the mechanism in position to open one of the gates.

The same reference characters are used to designate the same parts in the several figures of the drawings.

Reference character A indicates a horizontal base or supporting-frame upon which is mounted a casing B. Any suitable means may be provided for securing the casin B to the upper surface of the base A, such, ior instance, as laterally-projecting ears I), (see Fig. 2,) through which bolts extend.

The casing B is preferably of substantially the shape best shown in Fig. 7 and comprises an enlarged opening at the top thereof, above which is supported a hopper J, and two discharge-openings at its bottom near the ends thereof. The discharge-openings formed between the ends of the casing and the adjacent inclined portions of thebottom wall D are located above openings A and A through the base A. The small hoppers or funnels a and a are mounted upon the base A and surround the openings A and A therethrough. Partitions b and b are located within the casing B, thereby forming main supply-passages B and B between such partitions and the end walls of the casing and also forming supplemental supply-passages between such partitions and the bottom wall D of the casing. The upper ends of the partitions b and b are bent inwardly and downwardly, as shown in Fig. 7, to form a chute leading to the supplementary passages.

ends of the main supply-passages B and B Swinging gates O and C close the lower and are provided with ears extending on either side of and pivoted to the casing B. Each of the gates is provided with a weight C, adjustably mounted upon a screw-threaded rod, the tendency of such weight being to swing the corresponding gate closed to inter cept the fiow of material through the corresponding main supply-passage. An adjustable stop 0 is mounted upon the base A, upon which each weight C rests when the gate to which it is secured is closed.

Extending through the casing B are parallel shafts e and c journaled in bearings formed in brackets e e, secured to the opposite side walls of the casing B. Fixed upon the portions of these shafts within the casing B are disks E andE respectively, provided with recesses in their peripheries, adjacent recesses being separated by teeth curved in the direction of rotation of the disks. The radius of each disk is such that the teeth on the periphery thereof pass in close proximity to the respective sides of a partition d, projecting upwardly from the bottom wall D of the casing B. The disks are also so spaced apart that the chute formed between the inturned upper ends of the partitions b and terminates immediately above the adjacent peripheries thereof. The corresponding ends of the shafts e" and c projecting through the bearing e at one side or the casing. are pro vided with meshed gear-wheels F and F", while the portion of one of such shaftsas, for instance, e which projects thro gh the beareaaeee meshed gear-wheels H and H journaled upon stub-shafts supported by the base A. Rigidly secured to the hubs of the gear-- wheels H and H are radial arms h and 72?,

each of which is provided with an inwardlyprojecting stud.

Pivotally mounted upon the same side of the base A are two levers K and K having inwardly-projecting curved ends adapted to be engaged by the respective studs on the ends of the radial arms h and 7L2. The outer ends of each of the levers K and K is provided with a weight K. Pivotally supported on lugs projecting upwardly from the levers K and K are spring-actuated triggers 7c and k which are adapted to swing outwardly-that is, toward the respective weightsagainst the tension of their 0011* trolling-springs, but which cannot swing inwardly from the positions shown in Fig. 4. When the levers K and K are oscillated through engagement with the corresponding studs on the arms h and 72, the triggers 7c and k are adapted to pass behind and engage studs 0 and c fixed upon the gates C and C respectively. Each of the levers K and K is provided with a boss through which extends a vertical screw-threaded opening, in which is adjustably mounted screw-threaded stop is, adapted to project below the respective lever and engage the upper surface of the base A to limit the downward movement of the lever.

L and L designate scale-beams the opposite ends of which are provided with inwardly-extending parallel arms Z Z and Z Z respectively. Lugs a and a depend from the base A and serve as supports, to which are pivoted the inwardly-extending arms of the scale-beams. Each scale-beam is provided with an outwardly-extending screwthreaded rod upon which is adjustably mounted a secondary weight L. Each scalebeam is also provided, preferably at an intermediate point thereon, with outwardly-projecting arms L and L upon which are mounted the main weights L and L", respectively, by any suitable means-such, for instance, as bolts or rods Z and Z, respectively. The weights L and L are removable, so. that they may be replaced by weights corresponding to the quantity of material which it is desired shall be weighed upon the machine.

Pivotally supported between the inner ends of the pairs of arms Z Z and Z Z are re- M is provided with a central partition m,-

above which is pivotally mountedia guide to direct the-material into one or the other of the compartments of the respective recep-.

tacles. Such guides are shown in Fig. 7 at m and m and each consists in two trough-shaped portions arranged back to back and rigidl secured to rods m and m the latter exten ing through andbeing journaled in thewalls of the receptacles. Fixed upon the corresponding ends of the rods m and m*, which project through the weighing-receptacles,

' are short levers M and M, to the opposite ends of which are pivotally connected pairs of links n and M. The lower endscf each pair of links are pivotally connected to either side of the fulcrum of an oscillating bottom of the corresponding receptacle. Such bottoms are designated by N and N and are pivotally mounted upon the re ds n and n which are supported at their opposite ends by ears depending from the side walls of the receptacles. The oscillating bottoms are of such shape that when in one position one compartment of the corresponding receptacle will be closed, while the other compartment will be opened, and through the interposed pair of links the guide at the top of the receptacle will be correspondingly oscillated to guide the material into the compartment which is closed at its bottom.

Located below the weighing-receptacles is a-frame P, which may be conveniently supported by means of posts P, depending-from the corner-bosses a of the base 'A, the frame P being provided with a laterally-projecting flange having corner-bosses p, which are rigidly secured to the lower end of the posts in any suitable manner. The frame P consists in side and end walls, preferably slightly tapered inwardly, to the lower edges of which are secured the upper endof a funnel P into which the measured material is discharged from the compartments of the weighing-receptacles. 1) indicates a transverse partition extending between the side walls of the lower frame P.

Each of the weighing-receptacles M and M has pivoted onthe exterior of one end thereof a latch 0, provided with a downwardly-extending lug 0, adapted to engage one of the notches n, formed in the upper edge of a bracket N, rigidly secured to the oscillating bottoms of the receptacle. The bracket N is preferably bifurcated at its lower end and connected at either side of the fulcrum point of the corresponding bottom.

Two notches n are provided in the l and s the lug on the latch O and retain the bottom of the receptacle in either position to which it may have been oscillated. Rigidly secured to the top flange of the frame P are tripping-fingers. O 0, one of such fingers being located substantially in alinement with the interior partition m in each of the weighing-receptacles. Each tripping-finger is provided with an inwardly-projecting end 0, which extends beneath the inner or free end of the corresponding latch 0, so that upon each receptacle being sufficiently depressed by the weight of the material therein the inturned end of the tripping-finger will be engaged by the inner end of the latch O and the lug 0 on the latch thereby lifted out of the engaged notch on the bracket N, permitting the weight of the material to oscillate the bottom of the receptacle in position to discharge the material from one compartment and close the other compartment.

Projecting horizontally from one side of the base A are arms A and A, which are provided with downwardly-extending end portions, to which are rigidly secured weights A and A Such weights are for the purpose of-giving stability to the apparatus and pre-' caused by the filling and discharging of the I receptacles with the material which is being Weighed. Mounted above the weights A and A and adjustably secured to the ends of the arms A and A are stops a and a), upon which the ends of the arms L and L of the respective scale-beams rest after the respective receptacles supported by the scalebeams have been discharged.

Lugs A and A project upwardly from and are preferably formed integral with the arms A and A. Levers R and R are fulcrumed upon the lugs A and A at points intermediate of their ends. From the outer'ends of such levers depend links 1" and T the lower ends of which are provided with loops, into which extend rods Z and Z res ectively, which arefixed to the outer ends 0 the arms L and L of the scale-beams. Screw-threaded rods 8 and s are supported in brackets extending upwardly from the levers R and R Weights S and S are adjustably mounted upon the respective screw-threaded rods 8 The brackets which support the screw-threaded rods extend upwardly from portions of the levers R and R intermediate of their. fulcrums and their inner ends.

T and T designate tripping device s pivotally supported at points intermediate of their ends upon brackets t and t fixed upon the supporting-frame A. The inner ends of the tripping devices extend beneath the joints of pairs of links U. and U Each pair of such links is pivoted at one end to one of the ates C and C and at its other end to a brac et a or u fixed upon. the supportingposition shown in Fig. 6. I

Pivotally mounted upon the outer side of each of the arms A and A is an oscillating guide V, having a racewa r in which is located a ball or other gravity device X. A rod V projects from the guide V in an opposite direction from its fulcrum to that of the raceway and has adjustably mounted there on a weight 12. Projecting from the outer end of the raceway 1s a stud or screw c, which extends beneath the returned upper end of a bracket w, the lower end of which is rigidly secured to the upper surface of the arm of the corresponding scalebeam. An inclined lug W is fixed upon'the upper surface of each scale-arm in alinement with the raceway in the guide V. Located in alinement above the lug W is a stop Y, which depends from and is adjustably supported by a lug y, piojecting laterally from thebracket A upon the arm A The operation of my invention is as follows: The material to be weighed is deposited in the hopper J and flows therefrom into each of the main passages B and B and also through the chute between the inturned ends of the partitions l) and 11 into contact with the inner peripheries of the disk E and E Rotary motion is imparted to the shaft e by any suitable power connection such, for instance, as a belt engaging the pullcy F. The rotary motion imparted to the shaft e is transmitted to the shaft e by means of the meshed ear-wheels F and F and is also transmitte to the m'eshed gearwheels H and H through the gear-wheel G, interposed between the pinion f on the shaft 6 and the gear-wheel H The rotation of the gear-wheel H carries with it the radial arm 72, and the stud on. the end thereof, which latter engages-the innerend of the lever Khandforces thesame downwardly, thereby lifting the weight K on the opposite end of the lever. Such oscillation of the lever K swings the trigger 15 back of the stud c on the gate C as shown in Fig. 8. When the stud on the arm k passes out of engagement with the inner end of the lever K the weight K instantly swings the lever back to the position shown in Fig. 4 and through the engagement of the trigger is? with the stud c opens the gate 0 the latter being retained open by the links U assuming an alined position, such as shown in Fig. 6. The material then passes through the main supply-passage B into a compartment of the weighing-receptacle M the material being guided into such. receptacle by the guide m as clearly indicated in Fig. 7. Upon sufiicient mate- .X only remains in position to rial accumulating in the compartment of the receptacle M to overbalance the weight L on the scale-beam L the latter is swung into the position. shown in Fig. 3, in which the downward movement of the receptacle has been limited by the inclined lug W on the scale-beam arni L", gripping the gravityrball X against the stop Y. In such position the lowering of the weighing-receptacle has not been suflicient for the tripping-firiger O to elevate the latch 0 out of engagement with the notch in the bracket N on the oscillating bottom of the receptacle. The gravity-ball further downward movement 0 the weighing-receptacle long enough to prevent the downward momentum of such receptacle lowering the same sufiiciently to trip the bottom thereof and discharge the material, whereu. on the ball rolls from between the incline lug W and the stop Y and permits the gradual lowering of the receptacle as the material is supplied thereto by the constantly rotating feeding-diskE until the predetermined amount of material has accumulated in the compartment of the receptacle, lower ing the latter sufiiciently far to cause the tripping-finger O to disengage the latch O and permit the weighed material to swing the oscillating bottom N into position to oaen the compartment which has received t e material, thereby discharging the same through the frame l? and funnel P The lowering of the receptacle from the position shown in Fig. 1 to that shown in Fig. 3 is due not only to the material delivered thereto, but also to the weight Si'which lifts upwardly upon the outer end of the arm L of the scale-beam L through the link W, the loop at the lower end of wt ich surrounds the rod 1, fixed to the lever on the scale-beam. The amount of material supplied to the receptacle prior to its lowering into the position revent the shown in Fig. 3 is therefore less tl: an the predetermined amount to be weighed by a quantity corresponding to the weight S When the receptacle settles to the. position shown in Fig. 3, the lever R has swung to such a position that its free end has engaged the adjacent end of the tripping device T and oscillated the latter, so as to break the knee-joint of the links U thereby permitting the gate C to be instantly closed by the weight 0, carried thereby. The delivery of tlfie material to the weigh ing-receptacle after tle parts have assumed the position shown in Fig. 3 is consequently due entirely to tile constantlyrotating disk E wl-ich completes the predetermined amount of material in tlce receptacle, causing the same to lower tlte necessary degree to trip the bottom tliereof. The ball X is retained out of the path of the lug W after the parts have assumed the position shown in Fig. 3, by reason of the weight 12., which oscillates the raceway v to such an inclined position that the gravity-ball X rests "tie bracket N on the tilting bottom. The

tilting of the bottom of the receptacle through the interposed pair of links M oscillates the guide m about its pivotal rod m, so

hat the material flowing from the disk E is at once diverted into the empty compartment of the receptacle. The discharge of the material from the receptacle permits the weight L to at once elevate the receptacle and bring the outer end of the scale-arm L into contact with the adjustable stop a The'lowering of the scale-arm oscillates the raceway through the bracket 10 back to the position shown in Fig. 1 and through the en gagement of the rod 1 with the link r oscillates the lever R to the position shown in Fig. 1., and thereby'elevates its free end above the tripping device T After the gearwheels H and H have been oscillated through one hundred and eighty degrees from the position shown in Fig.4 the boss on the arm 71. engages the inner end of the lever K and oscillates the same, so that the weight K on the end thereof is elevated and the trigger 7c engaged behind the stud o on the gateC in position to open such gate upon the stud on the arm h passing out of contact with the inner end of the lever K. The material is consequently delivered to one of the compartments of the weighing-receptacle M through the main delivery-supply B until the partial lowering of such receptacle has oscillated the scale-beam and permitted the. supplementary wei ht S to oscillate the lever R and break t .e knee-joint of the links U, permitting the gate 0 to close. The complete lowering of the receptacle is interrupted by mechanism similar to that above described in connection with-the o eration of the weighing-receptacle M .and t e completion of the predetermined amount in the receptacle is effected by thecontinuous feed due to the constant rotation of the disk E. Upon the predetermined amount of material being completed the receptacle is lowered, so as to discharge the weighed'material' from the compartment and close the adjoining compartment into which the material flowing from the disk is directed by the posi-' tioii of the guide m.

' It will be noticed that the respective supplementary weights S and S merely aid the material in the receptacles in oscillating the scale-beams until they assume the positions taryweights S and S shown in Fig. 3, at which time the levers R and R come to a rest upon stops upon the arms A and A of the frame, and the further oscillation of the scale-beam is due entirely to the material delivered to the receptacle as the continued upward movement of the outer end of the arm L or L merely lifts the rod Z or Z upwardly within the loop at the lower end of the link r or T From the foregoing description it will be observed that the material to be weighed is alternately supplied to two receptacles and.

delivered alternately into the two compartments of each receptacle. Consequently the capacity of the machine is greatly multiplied,

especially as the completing feeding devices, consisting in the disks E and E constantly deliver material into one compartment or the other of both receptacles. The rapidity of operation is dependent upon the speed of ro tation of the meshed gear-wheels H and H, which carry the arms having studs on their ends, which, through the cooperating levers K and K and the triggers thereon, efi'ect the alternate opening pfthe gates O and 0?. The speed of rotation of such gear-wheels with relation to the speed of rotation of the powerdriven shaft 6 maybe varied by Varying the size of the pinion or small gear-wheel f, which is permitted byreason of the adjustable bearing of the gear-wheel G, interposed between such inion and the gear-wheel, H It is obvious, however, that thegear-wheels H and H should not complete a-revolution until the predetermined quantity of material has been weighedand discharged from the corresponding receptacles, and therefore the proportion of the predetermined amount of material supplied to the receptacles by the secondary or completing feeding devices must only be such as to ermit the redetermined amounts being de ivered to t e receptacles during the time required for the rotaby the supplementary or completing devices is determined by the respective supplemen- When they are adjusted upon their supporting screw-threaded rods .9 and s awaynfrom the fulcrums of the, levers R and R the receptacleswill'be lowered to the positions shown in Fig. 3 and the controlling-gates closed after a less supply of material has passed than would be supplied through such passages were the positions of such weights nearer the fuIcrumSof the levers R and R In other words, the adjust- "ment of the weights S and S determines the proportion of material which is to be supplied by the completing feeding devices after the gates have closed the main supply. It will be further observed that by adjusting the stops a and a, which limit thedownward movement of the outer ends of the levers L and L of the respective-scale-beams, the promensurate with the character of the material.

portions of the material delivered to the compartments of the receptacles by the main supply and completing supply may also be varied. For instance, when the stops are adjusted upwardly the weights S and S occupy positions farther from the center of gravity of the fulcrums of the levers R and 1t ,'and hence exert more power to aid the material in the receptacles in swinging the cooperating parts to the positions shown in Fig. 3, anc consequently increase the amount of the material supplied by the completing feeders.

From the foregoing description it will be observed that I have invented an improved power controlled automatic weighing machine in which the rapidity of action of the machine is not due to the material being weighed, which would cause, the action of the machine to vary according to the condition of such material, but is due to power-driven parts operating positively at predetermined lntervals. have invented a. weighing-machine which may be readily adjusted to suit the nature of the material which is to be weighed and to effect the greatest rapidity of action com- While I have described moreor less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents, as circumstances may suggest main supply, deflectors for directing the niaterial alternately into the compartments of each receptacle, and ireans for discharging a predeterir med quantlty of material from 1 said receptacles.
